Take it back to the security location you set, and it will automatically unlock, then reset the password.

Sorry but your only hope is to call Garmin. You will not find a solution to this online. Please see this link for more info:

The Security Location is the location that you set when you first enabled the Garmin Lock on your device. Returning to the Security Location will unlock your device. (Approximately 150 feet from that location)

If you have forgotten your PIN and Security Location please contact Product Support for assistance. Please note Garmin will require a copy of the receipt and there will be a charge to unlock the device as this issue is not covered by the warranty.

There is NO master reset code. Whoever told you this was wrong. You have to use your security location to unlock it. Otherwise, you have to send it in to Garmin with the original receipt from an authorized Garmin dealer. This is to prevent use of the unit in case of theft.

I think you have to send it back to Garmin. Liam

When you went through the password process you also had to set up your secret place in case you forgot your password. Go to your secret place and your Garmin will unlock and you can reset your password.
Hope this helps
